为了解、组织及整理整个香港区域的道路交通噪音资料,从而确定、量化及分折交通噪音的严重性.再鉴定相关的噪音缓解措施,香港环境保护署综合了数种先进的技术,包括地理信息系统、大型的电脑噪音模型、立体影像技术等,自行开发了一套以立体地理资讯系统为基础的区域噪音模型.从这个系统和模型计算出来的交通噪音地图.加上利用地理信息系统软件、人口分布的资料库和统计学方法的帮助,评估了整个城市总共有多少居民在那些区域受着多少交通噪音的影响.这些结果可以分析交通噪音的问题,继而决定未来噪音缓解设施及制定综合的计划.以应付这噪音问题.

To understand, collate and compile the traffic noise information on a territory wide basis so as to identify, quantify and analyse the scale of the problems and then evaluate relevant mitigation mea-sures, a fusion of novel technologies such as geographic information system (GIS), large-scale computa-tional noise modelling, three-dimensional (3D) visualization tools, etc., have been utilised to develop a 3D GIS based territory wide noise model. From the resulting traffic noise exposure maps, as well as the help of the GIS software, detailed population database and statistical method, the number of people af-fected by each levels of road traffic noise in each districts are all determined. These all help to evaluate the problem and formulate the future noise mitigation measures and comprehensive plan to tackle the problem. This paper describes the novel technologies such as the GIS technologies, the 3D large-scale noise modelling and the methods used to calculate the population affected by road traffic noise.
